The SR 52 project reduces identified environmental impacts through the preservation of plant and animal species. In addition, coordination between the project and the Lakeside River Park Conservancy provides for the establishment of a riparian habitat adjacent to the river. The project worked around bike paths and pedestrian trails that run alongside Forester Creek, offering users a safe and scenic tour of the valley.

The SR 52 construction improvements cost approximately $255 million and are funded by state (the California voter-approved Prop. 1B Transportation Bond), local (the San Diego region’s TransNet half-cent sales tax), and federal sources.

In addition to Managed Lane improvements, Caltrans and SANDAG are preparing for a future project to widen the corridor and accommodate further expected growth along SR 52.
